WHEEL-SUPPORT ATTACHMENT FOR DRAG SAYV.

Application filed May 11, 192G.- Serial No. 320,539.

T 0 all whom it may concern:

Be it known that I, EMIL G. Knees, a citizen of the United States, and resident of Tillamook, Tillamook County, State of Oregon, have invented a new andnseful Tm proveinent in lVheel-Support Attachments for Drag Saws, of which the following is a specification.

My invention relates in general to the well known type of portable drag-saw in which the saw is operated by an engine carried by the frame of the same. As well known, drag-saws of this type are now' being largely used due to the fact that they can be operated by one man, and are readily moved from place to place.

To facilitate the ready moving of these saws, the manufacturers make them as light as possible, but even the lightest allowable construction is of considerable weight.

The commercial typeof this drag-saw is generally mounted on a rigid angular frame, the vertex of which constitutes the base of the frame and is adapted to rest on the ground or other rigid support, while the opposite spread end of the frame is supported on the log to be sawed. When the drag-saw is to be moved to another place, it was necessary to pick it up bodily and carry it to such place. Such task obviously involves more or less hard work.

Therefore one of the main objects of my invention is to provide a wheel support by which the moving of the saw from place to place is facilitated, and which eliminates the hard work.

Furthermore, Idesire to make my attachment both simple and inexpensive.

' I attain my object by means of the device shown in the accompanying drawings, in which:

Fig. 1 is a side elevation of a gasoline drag-saw equipped with my attachment, and on which it is mounted ready for being moved;

Fig. 2 is a perspective view of my wheelsupport attachment; and

Fig. 3 is a plan view of my attachment.

In the drawings, a represents a portable gasoline drag-saw of the usual construction, in which 6 are the legs or sides of the angular frame, 0 is the engine, (Z the fly wheel, 6 the stroke-arm, and f the saw. The verteX of the angular sides of the frame is reinforced by a block 9 which forms a block or foot for the lower end of the frame of the drag-saw to rest on when the ing'worked. I

liaterally projecting handle-bars it are usually provided on this type of saw, the same extending perpendicularly from the sides of the saw frame at its lower end for the convenience of the carrier of that end.

My attachment is fastened to the saw frame by the aid of these handle-bars.

The attachment comprises a U-sha'ped yoke or frame preferably forged of a round, more or less, resilient metal bar, and having parallel arms 71, bent at an obtuse angle in a vertical plane and provided with ears 7' at their free extremities, constituting bearings adapted to be fastened on said handlebars 72. of the drag-saw frame.

The opposite end of the attachment frame, thatis, the closed end of the U, is so formed as to provide a transverse axle-portion k on which is mounted the truck-wheel Z. The frame portions 2" are bent at diverging angles as more clearly shown in Fig. '3, so as to hold the truck-wheel Z centrally between the sides of the attachment-frame and thus prevent it from interfering therewith. And intermediate the length of the attachmentframe the sides thereof are provided offset portions m constituting shoulders located and adapted to bear against the underside of the sides 6 of the saw-frame saw is beand support the latter adjacent its lower end. Said shoulders m also serve to hold the attachment frame against lateralmovement on the arms h of thesaw-fr me.

When the drag-saw is to be moved to another place, myattachment is arranged as shown in Fig. l. The sides Z; of the dragsaw frame will then rest on the shoulder or offset portions m of the frame of my attachment, and thereby holding the truck-wheel Z in fixed position relative to the saw frame. When my attachment is arranged. as shown in'Fig. 1, the drag-saw may be trundled about like a wheel-barrow; the ends of the saw-frame I) being seized like the handle bars of a wheel-barrow, and in this way balancing and guiding the drag-saw. When the drag-saw is tobe put to work again, the yoke and wheel are swung clockwise on the h and-hold bars 7t, so that my attachment will be so arranged as to be away from the underside of the saw frame and permit the block 9 of the latter to rest on the ground.

Hence my attachment does not interfere on said handle bars, the closed end of the sides being adapted to constitute a transverse axle portion, a wheel mounted on the latter, said sides being provided with offset portions constituting shoulders adapted to bear against and support said frame, said sides converging beyond said shoulders towards said axleportion to hold the wheel centrally between the sides.
